Hello bje,
Chemo is a teeter-totter, with an uneasy balance between constipation and diarrhea.
Be patient--if you're anything like me, you'll tip from one extreme to the other. It's not fun, but at least it has an end. Imagine those poor dialysis patients who go in three times a week for three hours every week of their lives.
Alyssa's advice--lots of water and fiber--is great.
Sorry you have to go through this.
Zach
